I love Herbes de Provence. They have such a wonderful distinctive flavor. I have tried almost every brand, and my absolute favorite is the Herbes de Provence sold by Williams Sonoma, in the little clay crocks. It has such a great flavor with an emphasis on lavender. If you want to make this vegetarian, omit the prosciutto, and use vegetable broth or water instead of the chicken broth. Add a little smoked paprika for the prosciutto's smokiness.
